摘要:

近百年来,伴随着矿石燃料的大量消耗,CO2的排放量剧增,引发了全球性的生态环境和社会问题。CO2同时也是廉价且可再生的碳资源,可作为生产醇、醚、酸、酯等重要化工品的原料。在众多吸引力十足的CO2利用路线中,作为清洁、可控的反应过程,电化学还原固定CO2技术在温和条件下生产化学品方面具有独特的优势。离子液体以其特有的性质被广泛用于电化学还原CO2过程,本文对目前国内外离子液体介质中电化学还原CO2的研究现状进行了综述,介绍了离子液体介质中电化学还原CO2的主要反应及基本原理;针对离子液体对CO2高效活化和转化等关键科学问题进行深入探讨,提出新型功能化离子液体的应用将成为CO2电化学还原领域的发展方向和热点。

Abstract:

The increasing emission of carbon dioxide (CO2) caused by unrestrained consumption of fossil fuel in recent hundred years has created globally ecological, environmental, and social problems. On the other hand, CO2 is also a cheap, abundant and renewable C1-feedstock, which can be converted into alcohols, ethers, acids and other chemicals. Compared to many other CO2 recycle techniques, electrochemical reduction of CO2 is more attractive for its clean and controllable process to produce chemicals under mild conditions. This review summarized recent research progresses in electrochemical reduction of CO2 in ionic liquid (ILs) electrolytes. First, major reactions and mechanism of CO2 electro-reaction in ILs were introduced. Then, scientific challenges of ILs on efficient CO2 activation and conversion were discussed. Finally, the application of new functional ILs should be taken as future research focus in CO2 electrochemical reduction.
